Learning to tune my RX2 8.4 (luff is 508 +/- 1). . . or failing. I have a
Chinook double-bolt 45 cm (aluminum) and the RacePro 490. The trim guide for
the RX2 is no help at all in trying to figure this out (thanks for the
multimedia CD NP, but I'd go for more tech stuff any day). So I went back to
the RX1 trim guide and used their guidelines. Is this my first mistake?
When I set the Chinook to 20 cm, it measures 17.5 from mast base to where
alum. meets the beginning of the pulley assembly. From the old RX1 trim
guide, seems this should be just about perfect. Problem is, I can't downhaul
it to the 18 cm mark, which is about 3 cm from the pulley. I'm > 1 cm.
short. More downhaul takes MASSIVE effort, even with a tool, and I'm still
nowhere near the max. I'm pretty sure my lines are run correctly, unless
something's totally changed.
I find I get a bit more downhaul if I downhaul partially, outhaul fully,
downhaul fully (or as best I can). This is my first race sail . . . is there
some secret sequence?
I'm pretty sure I'm under downhauled because my bottom batten won't rotate
like I think it should.
Do I lengthen my extension another 3 cm to get more leverage? Do I buckle
up, quit being a ***, and really haul the damn thing (way more than any
other sail I've had)? Do I need some crank tool? Am I measuring or doing
something else wrong? Is it possible to over downhaul and rage equipment to
